BARRIERS IN

IMPLEMENTATION

OF BIOGAS PLANT

BARRIERS IN IMPLEMENTATION OF

BIOGAS PLANTS

1. Food/Canteen Waste

Space constraints

The image of conventional Gobar Gas plant hascreated a fear of non-aesthetic & unhygienicconditions in the premises.

Odour nuisance.

Requirement / Adherence to stringent safety norms.

Reluctance to use Biogas due to its low calorific valuecompared to LPG / CNG.

Mental Attitude� Habit of disposal into municipal bins for years, so why pay for

systems now?

� Consideration of the system as energy generator rather than

waste disposal system.

2. Food Processing Waste

Quantity of waste generated is seasonal.Disposal as feed stock for cattle is comparatively easy

way out.

3. Municipal Solid Waste

Improper segregation of waste at the source.

NIMBY Effect (Not In My Back Yard).

Mental Attitude.

Lack of Awareness.

BIOMETHANATION

-THE MAILHEM WAY

TREATMENT PRINCIPLEThe basic concept of our design is based on a process

known as

UPFLOW ANAEROBIC SLUDGE BLANKET (UASB)

developed by Dr. Lettingah in the Netherlands.

It has been specifically modified by

MAILHEM ENGINEERS PVT. LTD., PUNE.

for the waste containing high percentage of

suspended solids. today, our technology is accepted as

MODIFIED UASB.

PRINCIPLE OF PSA BIOGAS PURIFICATION

� PSA BIOGAS PURIFICATION SYSTEM – is the

gas separation system with specially designed

adsorbent.� This adsorbent is called Molecular Sieves (MS) having

a micro pore on its surface and adsorb CO2, N2, H2S

and H2O molecules selectively under a certain

pressure.

� After adsorption process, adsorbent is regenerated

by depressurizing. These PSA systems produce the

Purified Methane enriched gas continuously by

repeating above adsorption and regeneration process.

A WAY FORWARD

Need to raise awareness amongst potential customers

about the benefits of alternate source of energy and

at the same time impact on environment .

Set up pilot projects on substrate not yet tried.

More practical approach to promote projects on the

part of all concerned authorities.

Pro-active role by the nodal agencies at state level.

Subsidies not only for capital expenditure but also for

operation and maintenance.

A WAY FORWARD (CONTD…)

Subsidies to be given on completion of project to ensure

successful commissioning.

Acceptance of completed project for subsidy within

twelve months of commissioning if promoter has not

applied for subsidy.
